Thank you for viewing! These are gold, nickel-free, hooked earrings with a loop. They do not contain nickel, which is one of the causes of allergies. I think you can use them with more peace of mind than plated earrings♡ * 100 pieces, 50 pairs ♡Product Description♡ As these are overseas products, there may be some variations in the manufacturing. Please refrain from purchasing if you are nervous or do not understand overseas products. These will be shipped in simple packaging. If you need packaging materials, it will be an additional 50 yen. I also sell ribbon charms, heart hoops, A-grade glass stones, twisted charms, openwork parts, stars, hearts, initials, etc. (o^^o)♡ Thank you!♡
